Overview
The AT91SAM7XC512B-AUR, produced by Microchip Technology, is a member of the SAM7X series of microcontrollers. It is based on the 32-bit ARM7TDMI processor and is functionally and mechanically equivalent to the AT91SAM7X512B, with the additional feature of AES/TDES crypto processors. This microcontroller operates at a maximum speed of 55 MHz and features 512KB of flash memory and 128KB of SRAM. The device includes a variety of peripherals such as USB 2.0 Full Speed device port, Ethernet MAC 10/100 port, CAN 2.0A and 2.0B compliant controller, two USART, UART, two SPI, SSC, TWI (I2C), three 16-bit timers, and an 8x10-bit ADC. The typical core supply is 1.8V, with I/Os supplied at 1.8V or 3.3V and 5V tolerant. An integrated voltage regulator allows for a single supply at 3.3V. The device is available in 100-lead LQFP and TFBGA packages.
